Laszlo Ersek e1b59e085a EmbeddedPkg/Universal/MmcDxe: "fix" CloseProtocol() call in BindingStop()
The 3rd and 4th parameters of the CloseProtocol() call are wrong.

Given that we're not dissociating a child controller from a parent
controller (= closing a BY_CHILD_CONTROLLER open), but closing a BY_DRIVER
open, the 4th parameter (ControllerHandle) should equal the 1st parameter
(Handle).

It's unclear why this code hasn't crashed before.

Note that the patch doesn't fix the underlying driver model bug. I don't
understand what the loop in MmcDriverBindingStop() attempts to do. Is this
driver supposed to be a bus driver? It seems to create new handles, and to
append device path nodes. But it doesn't set up proper parent/child
protocol opens, and it doesn't close them.

Laszlo Ersek 7b6ceb4d3b EmbeddedPkg/AndroidFastbootTransportTcpDxe: fix DestroyChild() call
- The 2nd parameter of EFI_SERVICE_BINDING_CREATE_CHILD is:

  IN OUT EFI_HANDLE *ChildHandle

- The 2nd parameter of EFI_SERVICE_BINDING_DESTROY_CHILD is:

  IN EFI_HANDLE ChildHandle

Fix the DestroyChild() call in TcpFastbootTransportStop().

This is an actual bugfix; I don't know why the current code doesn't crash.
Perhaps the function is never reached in practice? (It could be tied to an
error path.)

Dandan Bi 82e0c422b2 EmbeddedPkg: Unload image on EFI_SECURITY_VIOLATION
For the LoadImage() boot service, with EFI_SECURITY_VIOLATION retval,
the Image was loaded and an ImageHandle was created with a valid
EFI_LOADED_IMAGE_PROTOCOL, but the image can not be started right now.
This follows UEFI Spec.

But if the caller of LoadImage() doesn't have the option to defer
the execution of an image, we can not treat EFI_SECURITY_VIOLATION
like any other LoadImage() error, we should unload image for the
EFI_SECURITY_VIOLATION to avoid resource leak.

This patch is to do error handling for EFI_SECURITY_VIOLATION explicitly
for the callers in EmbeddedPkg which don't have the policy to defer the
execution of the image.

Loh, Tien Hock c49f298d28 EmbeddedPkg/MmcDxe: Enable 4-bit mode even if SD_HIGH_SPEED is not supported
If SD doesn't support SD_HIGH_SPEED, function should still continue to
setup SD to go into 4 bits more if it is supported. Currently, the code
inadvertently exits early, but with a EFI_SUCCESS return code, and so
execution proceeds without ever attempting to enable 4-bit mode.

Since not having SD_HIGH_SPEED support is not an error, downgrade the
message that reports this to DEBUG_INFO.

- Also harmonize variable name to match the one used in LibSetTime.
LibSetTime():
- Address possible underflows if time is set to start of epoch.
- Ensure that time being read does actually match time that was manually
  set (plus the time elapsed since), by subtracting number of seconds
  since reset.

[*] This fixes a build breakage, since one of these variables was set but
    never used, triggering a compiler diagnostic at some optimization levels.

Haojian Zhuang 1df5fb2d83 EmbeddedPkg/Drivers: add virtual keyboard driver
This driver is used to simulate a keyboard. For example, user
could read GPIO setting or data from RAM address. If the value
matches the expected pattern, it could trigger a key pressed
event.

User needs to implement hooks of PLATFORM_VIRTUAL_KBD_PROTOCOL.
There're 4 hooks in this protocol.
Register(): Quote the interface that user needs. For example, user
needs to locate GPIO protocol if he wants to simulate a GPIO value
as a key.
Reset(): Do the initialization before reading value.
Query(): Read value. If the value matches the expected pattern,
trigger a key pressed event.
Clear(): Clean the value if necessary.

Laszlo Ersek 7ab26d5180 EmbeddedPkg: introduce NvVarStoreFormattedLib
Some platforms don't format a variable store template at build time;
instead they format the non-volatile varstore flash chip during boot,
dynamically. Introduce NvVarStoreFormattedLib to enable such platforms to
delay the "variable read" service drivers until the platform specific
module(s) report that the variable store has been formatted.

The platform-specific module that performs the formatting during startup
is usually an FVB or MM FVB driver. Under the proposed scheme, it becomes
responsible for installing gEdkiiNvVarStoreFormattedGuid with a NULL
interface in the protocol database. In turn, the platform DSC will hook
NvVarStoreFormattedLib into the variable service driver, to make the
latter wait for the FVB driver. Platforms that need not delay the variable
service driver like this may still use the same FVB driver;
gEdkiiNvVarStoreFormattedGuid will simply be ignored.

Ard Biesheuvel 44e6186eea EmbeddedPkg/FdtLib: incorporate missing overlay support
Commit a099239015 ("EmbeddedPkg/FdtLib: Update FdtLib to v1.4.5")
updated our FdtLib implementation to a more recent upstream version,
but omitted fdt_overlay.c due to its ambiguous licensing situation.
This has been resolved now, so take the latest upstream version of
the file (which received no other modifications in the mean time)
and add it to FdtLib.

Note that fdt_overlay.c has a dependency on strtoul() which EDK does
not provide natively, so add a private implementation that wraps the
BaseLib routines that do roughly the same.
